摘要
针对城市河道传统护坡中的硬质化护坡、高坎陡坡和开敞缓坡,分析了它们的特性,在此基础上结合合肥市十五里河护坡实际情况,提出了挂网铺草皮、荣勋挡墙和植物护坡的改造方案,并进行稳定性、经济性、生态景观性分析。结果表明,各方案的边坡稳定性、生态景观性均满足要求;从经济性上看,总体上植物护坡的成本最小,硬质化护坡改造次之,而高坎陡坡中的生态砌块挡墙造价较高,但相比于传统的浆砌块石直立挡墙,在生态性等方面表现出明显的优势,在今后的挡墙修建时应优先考虑。本研究可为河道生态护坡建设提供参考。
In view of hard slope protection, high and steep slope, open and gentle slope of traditional slope protection for urban river, the paper analyzes their characteristics, and proposes the transformation plans of hanging net and laying turf, Rongxun retaining wall and plant slope protection based on the actual situation of the Fifteen Mile River slope protection in Hefei City. The paper also analyzes their stability, economic, ecological landscape features. Results show that the slope stability and ecological landscape of schemes can meet the requirements; from the point of view of economy, overall plant slope protection cost least, then hard slope transformation comes the second, and ecological retaining wall block of high and steep slope cost is higher, but compared to the traditional masonry upright retaining wall, it shows obvious advantages in terms of ecology and we should give priority to it at building the retaining wall in the future . This study can provide reference for the construction of ecological protection.
